p. 101. 
Dredged from Trinkitat Harbour. One of the most common Sargassa in 
the Red Sea. Recorded both by Zanardini and Piccone from Suez, Akaba, 
Tor, &e. 
14. Sargassum Latiroitum, J. Ag.; J. G. Agardh, l. c. p. 103. 
Dredged from 9 fathoms in Suez Bay. Recorded by Zanardini from the 
same locality. Hauck records a var. canzibarica from the Somaliland Coast, 
but the present plant agrees more closely with the type itself. 
15. SarGassum crispum, Forsk. 
Suez Bay. Recorded also by Zanardini from the same locality. 
16. SARGASSUM SUBREPANDUM, J. Ag. 
Suez Bay. Trinkitat. 
17. CYSTOSEIRA MYRICA, J. Ag. 
Several fragments referable to this species occurred in the collections. 
The species is described by Zanardini as “in mari rubro vulgatissima.” 
18. HypROcLATHRUS CANCELLATUS, Bory. 
Dredged from 10-12 fathoms at Khu Sinab. Recorded by Zanardini 
from Suez, Akaba, and Tor. 
19, Paprna pavonta, J. Ag. 
Suakim, Suez Bay, and one young plant from Trinkitat. 
20. ZONARIA SCHIMPERI, Kiitz. 
Suez Bay. Iam a little doubtful of this identification as the plant is a 
young one, but it agrees with the description given by Zanardini, who records 
it from the same locality. |
